Sarcasm - Can a character with no Electronics skill even use a computer?
At the earliest Tech Levels (TL6 - 7) societies, Electronics Researcher skill would have been the only way of operating a computer.
Then there was stuff like high-level programming languages, and
Computer Literacy as an Admin specialisation happened.
Also Windows, Icons, Menus and Pointing Devices (WIMP) meant that nearly everyone could "navigate" such a device.
Serious question - Do you need to make an Electronics skill check to use an Expert Program?
It helps to start asking what an Expert Program/System really is, before delving into the question.
An Expert System is a computer program that emulates the functioning of a human "expert". It was seen as being the future of AI back in the 70s/80s. However, because of the Expert System Quirks, they fell out of fashion and gave way to modern Large Language Models (LLM), Artificial Neural Networks (ANN) and Decision Support Systems (DSS).
Some of the Expert System quirks are:
Cost of acquiring knowledge from a human "expert."
Exponential increase in size when increasing the expert rulebase.
The difficulty of updating the expert rulebase with new abilities.
Difficulty in verifying rule consistency.
The programming languages of Expert Systems/Programs haven't been learned by successive generations.
Expert Systems might be able to perform as an "expert" in Interpretation, Prediction, Diagnosis, Design, Planning, Monitoring, Debugging, Repair, Instruction, Control. In other words, providing advise to an operations researcher, of some kind. Not really intended for the novice - but hey-ho, this is science fiction, so maybe it will happen that an untrained novice in a specific skill will benefit from such an "Expert" Program. That is kind of happening now, albeit, not with Expert Systems, but with LLM, ANN and DSS.
Also another grey area is the distinction between Intelligent Systems and Expert Systems. Expert Systems only give "advise." Intelligent Systems tend to be machines that are autonomous actors or doers. On the surface, it looks like any Traveller referee could handwave the differences, and just lump everything together as an "Expert Program." Except I wonder if that confuses people on what are the limits (and quirks) of these things are? You could say the answer depends on your type of sci-fi, or you could say that the game needs a more gamified version of what computers and software can do.
Sorry for rambling on.
